PROBLEM TO BE SOLVED: To suppress performance deterioration of a turbocharger due to attachment of a sensor on a housing of the turbocharger.SOLUTION: A face on a blade 13 side of a portion of a compressor housing 12 of a turbocharger 1 where a sensor 22 is installed is formed with a material 15 which can be shaven by the blade 13 at the time of rotation of a compressor wheel 14. In a condition where the face is shaven by the blade 13, passage of the blade 13 at the time of the rotation of the compressor wheel 14 can be detected by the sensor 22. At that time, as a mounting hole 11, etc. for fixing the sensor 22 does not need to be opened at a position on the face corresponding to a tip of the sensor 22, a dent is not formed on the face on the blade 13 side of the portion of the compressor housing 12 where the sensor 22 is installed, due to opening of the mounting hole 11. |
